Master Difficulty Can't Beat Intro

[barbapapa]

It's my first time playing this game and I'm trying it on Master. I'm currently on the intro at the part where Vaas says run forest run and you have to run away from the camp, but I keep getting shot. How tf am I supposed to do this, I've died like 30 times already.

I had to run on the right side in the beginning and then switch to the left side closer to the end. just tried it over and over and i got it. I almost gave up.
